?is the lsat getting easier or people just more prepared?

It seems like the newer LSAT require more right answers than the older ones to get a comparable percentile rank. So is this due to the test itself getting easier, test takers being more prepared, or both?

I think that the internet has destroyed the information asymmetries that previously dominated the LS application process and schools' placement, and, as a result, people are taking the test increasingly seriously. In 1998, you might have thought that the test was a minor component of your application. Today, you know that your future is riding on it.
